Recombinant human LUC7L2 protein is a genetically engineered form of the LUC7-like 2 (LUC7L2) protein, encoded by the *LUC7L2* gene in humans. LUC7L2 is a component of the spliceosome, a dynamic molecular machinery responsible for pre-mRNA splicing, a critical step in gene expression. This protein belongs to the LUC7 family, characterized by conserved RNA recognition motifs (RRMs) and roles in RNA binding. Studies suggest LUC7L2 participates in splice site recognition, spliceosome assembly, and may influence alternative splicing events. While its precise molecular mechanisms remain under investigation, LUC7L2 has been linked to transcription regulation, RNA metabolism, and cellular stress responses. Dysregulation of splicing factors, including LUC7L2. is implicated in diseases such as cancer and neurological disorders.
Recombinant LUC7L2 is typically produced using expression systems (e.g., *E. coli* or mammalian cells) for functional and structural studies. Researchers employ techniques like affinity chromatography (e.g., His-tag purification) to obtain high-purity protein. Its applications include investigating spliceosome dynamics, mapping protein-RNA interactions via CLIP-seq or RIP-seq, and exploring molecular pathways in diseases. Notably, LUC7L2 has emerged as a biomarker in acute myeloid leukemia (AML) due to its association with splicing anomalies in *KMT2A*-rearranged AML. Studying recombinant LUC7L2 aids in unraveling splicing regulation mechanisms and may inform therapeutic strategies targeting splicing defects. However, further research is needed to fully elucidate its biological roles and disease relevance.
